Description

The invention relates to a ramp system for installation in a vehicle, which allows the driveway of a movable object, in particular a wheelchair, in an interior of the vehicle, with at least one intermediate element, which is coupled to the vehicle and a Auffahrplatte, which with the at least one intermediate element is coupled, wherein the Auffahrplatte by means of a rotational movement about a first movable pivot axis of a vertical transport position in a horizontal stowage position can be brought.

Such ramp systems have been installed for some time in cars and vans, on the one hand to have the opportunity on the one hand a wheelchair user uncomplicated and easy driveway in the interior or the transport area of the vehicle, and on the other hand, sufficient storage space and a usable floor area in the Having a transport vehicle when no wheelchair user is transported.

Known ramp systems, see for example US 8 635 729 B1 or WO 2010/003387 A1 , are usually movable between three positions. In a first Auffahrposition the Auffahrplatte is inclined relative to a horizontal and thus bridges the height difference between the bottom-side retracting edge of the vehicle interior and the road or Gehwegebene. The inclined ramp allows the wheelchair user to roll into the transport interior of the vehicle independently or with the assistance of the nursing staff.

The platform is brought after the entrance of the wheelchair user in a transport position in which the Auffahrplatte is arranged substantially vertically. After reaching the destination the Auffahrplatte can be moved again from the vertical transport position in the inclined relative to a horizontal approach position to allow the wheelchair user to get out of the transport vehicle.

If the vehicle equipped with such a ramp system is not used to carry wheelchair users, the ramp system ramp can be brought into a horizontal stowed position. In this stowage position, the ramp plate lies in the floor area of the vehicle interior, so that a large part of the stowage space is available again.

In order to keep the inclination of the Auffahrplatte low in the driveway, you try a trailing edge in the vehicle interior, over which the wheelchair driver enters the interior, to arrange as deep as possible. It is regularly below the inside vehicle floor on which, for example, the vehicle seats are mounted, arranged. Thus, the Auffahrplatte in the stowed position is approximately on a plane with the inside vehicle floor, such ramp systems require intermediate elements that can compensate for the height difference between the entry edge and the inside vehicle floor. For this purpose, a plurality of mechanical elements are often used in known ramp systems. In known ramp systems, nested slide guides are used. The combination of a high number of parts and a complicated mechanism leads to an increased risk of failure or to an increased risk of malfunction or malfunction. Furthermore, the known mechanical implementations by nested slide guides lead to an increased risk of injury during the use of such ramp systems. Due to the variety of parts also the required space is increased. In addition, the complicated mechanism often requires non-production-optimized components, whereby the manufacturing cost of such ramp systems are increased.

The invention is based on the object at least partially to reduce the above-mentioned disadvantages and to provide a ramp system and a vehicle with a ramp system, which allow the vehicle in addition to the transport of wheelchair users also otherwise without loss of storage space to use.

The object is achieved in a first aspect of a ramp system of the aforementioned type, wherein at least one guide pin is arranged on the Auffahrplatte, which is guided in a longitudinal guide in the at least one intermediate element and at least one guide strut between the intermediate element and the Auffahrplatte is articulated. The Auffahrplatte is thus guided relative to the intermediate element by the guide pin in the longitudinal guide of the intermediate element and thus movable relative to this. In conjunction with the guide strut, the rotational movement of the ramp plate about the first movable pivot axis can be carried out by a simple and uncomplicated mechanism with a small number of parts compared to the prior art.

In a first preferred embodiment of the ramp system according to the invention, the ramp plate can be moved by means of a rotational movement about a second pivot axis from an inclined ramp-up position into the vertical transport position. The first movable pivot axis and the second pivot axis allow the mounting of the ramp system in a lowered relative to the floor of the vehicle interior level and thus a moderate angle of inclination of the Auffahrplatte in the Auffahrposition and leveling the Auffahrplatte with the inside vehicle floor in the stowed position. The inclination of the Auffahrplatte in the Auffahrposition is dependent on the ratio between the height to be bridged by the ramp and the length of the Auffahrplatte.

In a second preferred embodiment, the loading platform is coupled with preferably only two intermediate elements, which each have only one longitudinal guide and are arranged opposite to the outer surfaces of the loading platform. In this embodiment, two opposite guide pins are arranged on the loading plate, which are each guided in preferably only one longitudinal guide of an intermediate element. Due to the two-sided guidance of the Auffahrplatte an increased stability and thus an increased life is achieved.

In a further preferred embodiment of the ramp system according to the invention, the two intermediate elements are coupled by an intermediate plate. The intermediate plate is arranged in the Auffahrposition and in the transport position of the Auffahrplatte parallel to the Auffahrplatte and preferably comes into contact with the Auffahrplatte. The intermediate plate is aligned so spaced from the Auffahrplatte that this is the Auffahrplatte without the presence of a Slot extended. Preferably, the intermediate plate is arranged perpendicular to Auffahrplatte when the Auffahrplatte is in the stowed position.

The ramp system according to the invention is advantageously developed by two guide struts, which run parallel and are arranged opposite to the outer surfaces of the Auffahrplatte. The presence of guide struts on both sides has a positive effect on the stability of the ramp system during the approach ramp procedure between the different positions. In combination with the intermediate elements present on both sides and the guide pins engaging in their longitudinal guidance on both sides, the guidance precision of the loading platform is also improved.

In a further preferred embodiment, the first movable pivot axis coincides with the horizontal center axis of the guide pin or the guide pin. The orientation and arrangement of the first movable pivot axis is consequently limited by the longitudinal guides of the intermediate elements.

In a further preferred embodiment of the ramp system according to the invention, the at least one guide strut is arranged in the transport position along a vertical. Preferably, the at least one guide strut is inclined in the stowed position relative to a vertical, wherein the at least one guide strut in the Auffahrposition preferably has the same inclination relative to a horizontal as the Auffahrplatte. In the Auffahrposition and in the transport position, the guide strut is thus aligned parallel to the center axis of the Auffahrplatte, thereby a space-saving implementation of the movement mechanism is made possible. In the stowed position, the loading plate is supported particularly advantageous by the inclined arrangement of the guide strut, so that it can be loaded without further bearing or support elements. Since no further supporting or bearing elements are necessary, the ramp system on the one hand further simplifies and on the other hand still be charged with loads.

In a further preferred embodiment of the ramp system according to the invention, the at least one guide strut is in the transport position and in the Auffahrposition on the at least one intermediate element. By resting on the one hand reduces the space requirement and on the other hand reduces the risk of injury, since the risk of hand or Fingerquetschungen is reduced.

The ramp system according to the invention is advantageously further developed in that the vertical outer surfaces of the guide struts and the lateral outer surfaces of the Auffahrplatte are arranged in the same plane. Depending on the strength of the guide struts and the design of the outer surfaces of the Auffahrplatte thus a slim implementation of the movement mechanism can be achieved, so that the space required for the movement mechanism is reduced and / or a widened Auffahrplatte can find use in this embodiment.

In a further advantageous embodiment of the ramp system according to the invention, an intermediate element and a guide strut, which are arranged on the same side of the Auffahrplatte, together have a width of less than 20 mm, more preferably less than 15 mm.

The ramp system according to the invention is advantageously further developed in that the at least one guide pin is arranged in the transport position and in the drive-up position in a first end position in the at least one longitudinal guide. An end position is to be understood as a position in which the guide pin can not continue an executed movement in the longitudinal guide, since the movement is positively limited by the presence of an end edge. Preferably, the at least one guide pin is arranged in the stowage position in a second end position in the at least one longitudinal guide. The longitudinal guide can thus guide the guide pin between the first end position and the second end position.

In a further preferred embodiment of the ramp system according to the invention, the at least one longitudinal guide is partially bent. The curved design of the longitudinal guide the movement of the Auffahrplatte is influenced in the process between the two different positions. The curved guide on the one hand jamming the Auffahrplatte with other parts of the ramp system and / or the vehicle can be avoided and on the other hand, the gap opening between the intermediate plate and the Auffahrplatte be reduced in the stowage position.

The ramp system according to the invention is advantageously further developed in that the at least one longitudinal guide has an end seat at one end, which is preferably formed by a 90 ° arc in the longitudinal guide. The end seat allows the positive positioning and / or engagement of the guide pin in the Stowed position, so that the Auffahrplatte is secured in such a horizontal orientation that it can not be brought out of this position by applying vertical forces. This allows a safe loading of the ramp in the stowed position, without the risk that the Auffahrplatte moves by the application of vertical forces by loading the Auffahrplatte with objects in a different position.

Particularly advantageously, the ramp system according to the invention is developed by the fact that the Auffahrplatte can be locked in the transport position. This prevents unintentional movements of the loading platform. Consequently, safety in using the ramp system is increased.

The ramp system according to the invention is advantageously further developed in that a first locking mechanism locks and releases the method of the loading platform from the transport position to the loading position and / or a second locking mechanism blocks and releases the method of the loading platform from the transport position to the stowed position. The two separate locking mechanisms increase operational safety and reduce the risk of failure of the ramp system.

In a particularly preferred embodiment of the ramp system according to the invention, the first locking mechanism is adjustable via a first actuating lever and the second locking mechanism is adjustable via a second actuating lever. The separate operating levers, which can be operated manually, increase the ease of use of the ramp system and allow quick and easy handling.

In a second aspect, the object underlying the invention is achieved by a wheelchair access vehicle having a ramp system according to any one of claims 1 to 15.

Fig. 1 shows a ramp system 1, which is installed in a vehicle 2. In the inclined Auffahrposition 24, the Auffahrplatte 8 is inclined relative to a vertical plane and thus bridges the height difference between the road or the sidewalk on which the vehicle 2 is located and a lowered Retracting edge 9 of the interior 4 of the vehicle 2. The lowered entry edge 9 is arranged lower than the inside vehicle floor 11, on which for example, the driver and passenger seat is mounted. This height difference is due to a ramp-like driveway in the interior 4 of the vehicle 2, which has substantially the same inclination as the ramp plate 8 of the ramp system 1 in the loading position 24. Between the ramp 8 and the lowered entry edge 9, an intermediate plate 7 is arranged. The intermediate plate 7 connects the bilateral intermediate elements 6a, 6b (not in Fig. 1 numbered) with each other. The intermediate elements 6a, 6b are connected by means of guide struts 20a, 20b to the loading platform 8 or the outer surfaces 26a, 26b of the loading platform 8.

In Fig. 2 It is clear that the intermediate elements 6a, 6b are not only connected to the loading platform 8 via the guide struts 20a, 20b, but also into the guide pins 16a by longitudinal guides 18a, 18b (18b) which are arranged on the intermediate elements 6a, 6b , 16b (16b hidden) engage, which in turn are coupled to the Auffahrplatte 8. Auffahrplatte 8 and intermediate plate 7 are constantly inclined, in the example between about 15 and 25 °. The intermediate plate 7 terminates flush with the lowered entry edge 9 of the vehicle 2 on one side. The outer surfaces 30a, 30b (30b hidden) of the guide struts 20a, 20b are arranged substantially in the same vertical plane as the outer surfaces 26a, 26b of the Auffahrplatte. 8

In the Fig. 3 shown side view illustrates the inclination of the Auffahrplatte 8 relative to the horizontal plane in the illustrated inclined Auffahrposition 24th

The functional mechanism of the ramp system 1 is in Fig. 4 shown in a detailed view in the side view. A first movable pivot axis 10 in this embodiment corresponds to the central axis 28 of the guide pins 16a, 16b. In the illustrated inclined Auffahrposition 24 of the Auffahrplatte 8, the guide pins 16a, 16b are in a first end position 32 in the longitudinal guides 18a, 18b. The longitudinal guides 18a, 18b are partially bent or curved and have at one end an end seat 36, which is formed by a 90 ° bend or a 90 ° buckling of the longitudinal guides 18a, 18b. The intermediate elements 6a, 6b are pivotally coupled to the vehicle, wherein the pivotal movement of the intermediate elements 6a, 6b about the second pivot axis 22 is executable.

By coupling the Auffahrplatte 8 with the intermediate elements 6a, 6b through the guide pins 16a, 16b and the combination of longitudinal guides 18a, 18b and When the intermediate elements 6a, 6b pivot about the second pivot axis 22, guide pins 16a, 16b also pivot the ramp plate 8 about the second pivot axis 22.

By pivoting the Auffahrplatte 8, the in Fig. 5 and 6 shown transport position 12 of the Auffahrplatte 8 can be adjusted. The loading plate 8 is oriented substantially vertically in the transport position 12. In this illustration, the first operating lever 38 and the second operating lever 40 are arranged in a plane parallel to the Auffahrplatte 8, which is spaced in the direction of the rear vehicle closure of the Auffahrplatte 8.

The side views of the ramp system 1 in Fig. 7 and in Fig. 8 illustrate the vertical orientation of the Auffahrplatte 8 in the transport position 12. Since it only comes to a rotational movement of the Auffahrplatte 8 about the second pivot axis 22 when pivoting from the inclined Auffahrposition 24 in the transport position 12, the guide pins 16a, 16b are in the transport position 12th as well as in the inclined approach position 24 in the first end position 32 in the longitudinal guides 18a, 18b. Accordingly, the guide struts 20a, 20b parallel to the outer surfaces 26a, 26b of the Auffahrplatte 8 and the outer surfaces 30a, 30b of the guide struts 20a, 20b extend substantially in the same vertical plane as the outer surfaces 26a, 26b of the Auffahrplatte. 8

To move the Auffahrplatte from the transport position 12 in the stowed position 14, the Auffahrplatte 8 is moved about the first movable pivot axis 10. As in Fig. 9 shown, the Auffahrplatte 8 is arranged in the stowed position 14 substantially in a horizontal plane and includes substantially flush with the inside vehicle floor 11 from.

As in Fig. 9 and Fig. 10 is indicated, the intermediate elements 6a, 6b extend in the stowage position 14 of the Auffahrplatte 8 substantially in the vertical direction. The figure likewise shows that the surface of the ramp plate 8 which points upwards in the stowed position 14 is arranged in the stowage position 14 substantially in the same plane as the inside vehicle floor 11.

The side views 11 and FIG. 12 show that the first movable pivot axis 10 and the guide pins 16a, 16b have moved along the longitudinal guides 18a, 18b from the first end position 32 to the second end position 34. There the intermediate elements 6a, 6b have not changed their position during the change in position from the transport position 12 to the stowage position 14 of the loading platform 8, the guide struts 20a, 20b have been moved from their vertical orientation into an orientation inclined relative to the vertical. In the illustrated embodiment, the guide struts 20a, 20b in the stowage position 14, both with respect to the intermediate elements 6a, 6b and with respect to the Auffahrplatte 8 approximately at an angle of 45 °. In a manner not shown, the Auffahrplatte 8 may be supported in the stowage position 14 shown by the vehicle structure, preferably by means of a support or more supports.
